用于混砂的填充方法和填充装置
摘要：
当通过推压构件将混砂罐中的混砂推压到模具中时，从推压构件开始移动时开始监测施加于混砂罐中的混砂层的推压力并监测推压构件的移动位置。基于施加于混砂罐中的混砂层的推压力来识别混砂开始流入模具的推压开始时刻(t1)，以及识别推压构件在该推压开始时刻(t1)的推压起始位置(L3)。因此，准确地识别推压构件在混砂开始流入模具时的推压开始时刻(t1)和推压起始位置(L3)，所以提高了将混砂填充到模具中的填充评估的可靠性。
摘要（英）：

When pressing kneaded sand in a kneading sand tank into a mold by a pressing member, a pressing force applied to a kneaded sand layer in the kneading sand tank is monitored and a moving position of the pressing member is monitored from when the pressing member starts to move. A pressing start time (tl) at which the kneaded sand starts to flow into the mold is identified based on the pressing forceapplied to the kneaded sand layer in the kneading sand tank, and a pressing starting position (L3) of the pressing member at the pressing start time (tl) is identified. As a result, the pressing start time (tl) and the pressing starting position (L3) of the pressing member when the kneaded sand starts to flow into the mold are accurately identified, so the reliability of a filling evaluation of the kneaded sand into the mold is improved.
